Proper use of prilocaine and epinephrine
Your dentist or other trained health professional will give you prilocaine and epinephrine in a medical facility. It is given through a needle placed into the head and neck area or injected directly into your gums.
Prilocaine and epinephrine should cause numbness only to the area where it is injected. You may experience temporary loss of sensation or movement in the injected area. This type of numbing procedure is called local anesthesia. It is not meant to cause you to fall asleep or become unconscious.
Your mouth may be numb for several hours. To avoid injury after dental work, do not chew solid foods until normal feeling has returned to the area. Do not test the feeling in your mouth by biting or poking the treated area.
Precautions while using prilocaine and epinephrine
It is very important that your doctor check your or your child's progress closely while receiving prilocaine and epinephrine to see if it is working properly. Blood tests may be needed to check for any unwanted effects.
Prilocaine and epinephrine may cause a rare, but serious blood problem called methemoglobinemia. The risk may be increased in children younger than 6 months of age, elderly patients, or patients with certain inborn defects. It is more likely to occur in patients receiving too much of the medicine, but can also occur with small amounts. Check with your doctor right away if you or your child has the following symptoms after receiving prilocaine and epinephrine: pale, gray, or blue-colored skin, lips, or nails, confusion, headache, lightheadedness, fast heartbeat, or unusual tiredness or weakness.
Tell your doctor or nurse right away if you have the following symptoms with prilocaine and epinephrine: anxiety, blurred vision, depression, drowsiness, lightheadedness, nausea or vomiting, numbness and tingling of the mouth or lips, restlessness, ringing in the ears, speech problems, or tremors.
Prilocaine and epinephrine may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and require immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, mouth, or throat after receiving prilocaine and epinephrine.
Prilocaine and epinephrine may also increase your risk of having serious heart and blood vessel problems such as a heart attack, heart rhythm changes, or low blood pressure. Check with your doctor if you have chest pain or discomfort, pain or discomfort in the arms, jaw, back, or neck, dizziness, fainting, pounding, slow heartbeat, troubled breathing, or unusual tiredness or weakness.
Before you have any medical tests, tell the medical doctor in charge that you are receiving prilocaine and epinephrine. The results of some tests may be affected by prilocaine and epinephrine.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
